如何使用 PHP 和 MySQL 一次从一个表单中插入多个值答案

【问题标题】：How To Insert multiple values from a single form at once using PHP and MySQL如何使用 PHP 和 MySQL 一次从一个表单中插入多个值
【发布时间】：2018-12-08 20:18:55
【问题描述】：

我尝试使用 php 在 mysql 中插入多个名称及其对应的姓氏，但似乎有什么地方做错了。我尝试了谷歌和这个网站，但我还没有得到满足我要求的最佳答案。我也设法插入它们，但姓氏可能会转到错误的用户名，然后我决定删除该代码并开始一个新的。任何帮助将不胜感激。以下是我尝试过的。

 <form action ="dependant_Process_Trevor.php?memberid=<?php echo $_GET['memberid']; ?>" name="contactform"  method="post" id ="---contactform" >
               <input type="hidden" name ="memberid" value="<?php echo $_GET['memberid']; ?>" >
                <div class="box-header">

$recieved_by =($_SESSION['username']);

$id_passport =(isset($_POST['id_passport']))? trim ($_POST['id_passport']):'';
$tel =(isset($_POST['tel']))? trim ($_POST['tel']):'';

$address =(isset($_POST['address']))? trim ($_POST['address']):'';
$work_address =(isset($_POST['work_address']))? trim ($_POST['work_address']):'';
$comments =(isset($_POST['comments']))? trim ($_POST['comments']):'';
$cell =(isset($_POST['cell']))? trim ($_POST['cell']):'';
//cell convert to 27 


if(isset($_POST['submit'])){
foreach($_POST['name'] as $name)
foreach ($_POST['surname'] as $surname)
foreach($_POST['parent_type'] as $parent_type )


$count = count($_POST['name']);

    for($i = 0; $i < $count; $i++) {

【解决方案1】：

我觉得有几个问题，第一是这段代码大部分是多余的……

foreach($_POST['name'] as $name)
foreach ($_POST['surname'] as $surname)
foreach($_POST['parent_type'] as $parent_type )


$count = count($_POST['name']);

由于foreach() 没有{}，所有循环最终将只执行最后一行，这将始终相同。所以删除 3 个foreach() 循环，就可以了

$count = count($_POST['name']);

然后为每个循环设置值，你几乎拥有它（我认为）并且需要......

$name =  $_POST['name'][$i];
$surname = $_POST['surname'][$i];

最后你的测试看看它是否有效

if($query){

是不正确的，你应该检查所有的

$insert->execute(array(...));

语句返回true，这应该表明它们都已被创建。

【讨论】：

您能否将整个代码编译为单个单元而不是部分部分。感谢您的努力，先生，非常感谢
没什么大不了的，我原以为能够进行少量更改比大量代码要容易得多。
我进行了更改，它插入了数组文本，它给了我这个错误：Array to string conversion in .我认为这是我现在的问题，因为你设法让我找到了解决方案。
一件事是，如果您可以识别错误所在的行，则更容易找出导致错误的原因 - 如果您需要错误报告 - stackoverflow.com/questions/1053424/…
我认为我们现在必须将数组转换为实名而不是在bd中发布单词Array

【解决方案2】：

在@Nigel Ren 的帮助下，我终于得到了答案，一切都很好，这里就是答案。

if(isset($_POST['submit'])){
$surname = $_POST['surname'];
$name = $_POST['name'] ;
$parent_type = $_POST['parent_type'];
$count = count($_POST['name']);

if(is_array($name) && is_array($surname) && is_array($parent_type)) {
    for($i = 0; $i < $count; $i++) {
     var_dump($name[$i]);

$surname1 = $surname[$i];
$name1 =$name[$i];
$parent_type1 = $parent_type[$i];
